The `gitea.com/go-chi/captcha` package only exists for Gitea, so it moves into `modules/imagecaptcha`. - Reloading an expired challenge shows a new image instead of a broken one - Every answer is consumed on its first check - OpenID registration stops after a failed captcha --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
